Abstract

The invention discloses a double hot standby server system which includes an external network and a case, wherein the external network is two cascaded switches and an integration of two mainboards, a interconnection backplane, two network cards, a dual redundancy power supply, a redundancy fan and Redundant Array of Inexpensive Disks (RAIDS) is arranged in the case. The interconnection backplane comprises a CPCI (Conference Proceedings Citation Index) bus, a CPCI interface, a CPLD (Complex Programmable Logic Device) controller (namely Central Processing Unit) and a CPLD controller interface. The two mainboards are connected with the CPLD controller through the CPCI bus. The RAIDS are connected with the CPLD controller and the two network cards are connected with the CPLD controller. Every network card is connected with the two cascaded switches. The dual hot standby server system has the advantages of having a compact structure, a small volume and a high reliability.

Description

technical field [0001] The invention relates to a dual hot standby server system. Background technique [0002] The functions provided by computer server equipment mainly include scientific computing, data storage, communication interaction, information retrieval and display, etc. In addition to the improvement of functions and performance, the reliability of computer server equipment, low equipment integration, and low power consumption It has become an important direction of development at present. With the development of information technology, the dependence on computer server equipment in various fields is getting higher and higher, which inevitably requires computer server products to further improve their integration and reliability. [0003] The characteristics of the existing products are as follows: [0004] 1) Each device of the computer server is independently configured, and can be configured with independent human-computer interaction peripherals (such as: key...
